RESUMEN

Objective: Mobility prognosis is a key focus during rehabilitation following spinal cord injury (SCI). The goal of this study was to prospectively evaluate the clinical utility of the van Middendorp clinical prediction rule (CPR).Design: Observational studySetting: Inpatient rehabilitation unitParticipants: Physical therapists and their patients with acute SCI and SCI disorders (SCI/D) for whom long-term ambulation prognosis was judged difficult to determine.Interventions: N/AOutcome Measures: CPR-determined probability of ambulation, therapist reported clinical utility (yes/no), shared with the patient (yes/no), useful for motivation/setting realistic expectations, and Functional Independence Measure (FIM) Locomotion walk score.Results: Five therapists and 52 patients (8 non-traumatic SCI/D) participated. 91% had lesions classified as AIS C or D. The median [IQR] for CPR probability of ambulation was 96.0 [86.5,99.0] for traumatic SCI and 80.0 [64.5, 94.5] for non-traumatic SCI/D. Clinical utility was reported for 45% of those with SCI and 88% with non-traumatic SCI/D. Therapists with less experience were more likely to report clinical utility and share with their patients. Ambulation probability was higher for patients who did not meet their FIM goal. CPR probability was correlated with discharge FIM only for non-traumatic SCI/D.Conclusion: The CPR was not predictive of inpatient rehabilitation outcomes, in fact outcomes varied widely for individuals with similar probabilities emphasizing the importance of clinical judgement and continued need to identify individual factors that affect ambulation. However, greater utility in establishing prognosis and goal setting was noted for clinicians with less experience and for individuals with non-traumatic SCI/D.

RESUMEN

PURPOSE: Complex rehabilitation technologies (CRT) support independence for individuals with disabilities by enabling mobility for function, employment, education, and independent living. CRT service delivery is evolving, with changes to funding, provider qualifications, consumer needs, and technological advances. This scoping review investigated service delivery processes for individuals with disabilities who have a mobility impairment, while specifically identifying best practices, barriers, and unique features of health delivery policies and practices. METHODS: We used a framework described by Colquhoun et. al. for conducting scoping reviews, a six-step process that includes: 1) identifying the research question, 2) identifying studies, 3) selecting studies 4) data charting, 5) reporting results and 6) consultation. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) was also used for reporting results of the review. RESULTS: Common categories were identified and organised into a hierarchical structure of four categories and 16 sub-categories. The primary categories included "policy", "consumer", "service delivery", and "wheeled mobility devices". The sub-categories described funding sources, consumer and professional populations, service delivery guidelines, and types of mobility devices. Analysis indicated the data were from 21 countries and 14 combinations of funding sources, and the articles were primarily descriptive studies. CONCLUSION: This scoping review identified evidence from various countries, health systems, and stakeholder. Currently, this process does not proactively address the needs of individuals with mobility disabilities. The scoping review provides the foundation for the development of a novel policy on the provision of CRT services and devices to address these needs.Implications for RehabilitationExamination of national and international service delivery practices in diverse clinical and funding environments indicate various challenges and opportunities for improvement.CRT consumers are negatively impacted by current service delivery practices, including long wait times, lack of specialised clinical expertise, and limited consumer education opportunities.More consistent and widespread research is needed within the CRT provision industry to grow evidence-based practice related to complex rehabilitation technology and individuals with disabilities.

RESUMEN

STUDY OBJECTIVES: This study aimed to quantify the impact of excessive daytime sleepiness (EDS) on patient and patient's partner health-related quality of life in the form of utility values typically used in health economic evaluations. METHODS: A time trade-off study was conducted in a UK general population sample (representing a societal perspective) to elicit utility values, measured on a 0 to 1 scale, for health states with varying obstructive sleep apnea-associated EDS severity. In a time trade-off study, health states are described, and participants "trade off" time in a specific higher severity state for a shorter amount of time in full health. RESULTS: Overall, the sample consisted of 104 participants, who were interviewed and took part in the time trade-off exercise to elicit utility values for patient and partner residual EDS health states. The average utility score declined with increasing obstructive sleep apnea-associated EDS severity for both patient (no EDS, 0.926; mild EDS, 0.794; moderate EDS, 0.614; severe EDS, 0.546) and partner (no EDS, 0.955; mild EDS, 0.882; moderate EDS, 0.751; severe EDS, 0.670) health states. CONCLUSIONS: These results demonstrate the high impact that EDS in obstructive sleep apnea is estimated to have on patient and partner health-related quality of life.

RESUMEN

OBJECTIVE: To evaluate the reliability, standard error of measurement, minimum detectable change, and item-level consistency of the Transfer Assessment Instrument (TAI) version 4.0 when used to evaluate transfer quality remotely. DESIGN: Participants transferred from their wheelchair to a mat table (transfer 1), repeated this after a 10-minute delay to assess intrarater reliability (transfer 2), and repeated this 1-2 days later to assess test-retest reliability (transfer 3). Each transfer was scored in person by 4 raters and asynchronously by a remote clinician rater. SETTING: 2017 National Veterans Wheelchair Games. PARTICIPANTS: Convenience sample of 44 full-time wheelchair users (N=44). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: TAI total score, subscores (wheelchair setup, body setup, flight/landing), and item scores (15 items). RESULTS: Moderate to excellent reliability was found when scoring remotely for TAI total and subscores for intrarater (intraclass correlation coefficient (ICC(3,1)=0.687-0.854), test-retest (ICC(3,1)=0.695-0.836), and interrater reliability (ICC(3,5)=0.746-0.962). Remote rater total score and flight/landing subscore were greater (indicating higher transfer quality) compared to the average in-person raters (P=.021 and P=.005, respectively). There were no differences between transfers 1-3 in remote rater scores. Item-level percentage agreement between the remote rater and in-person exceeded the 75% cutoff for clinical utility for all items. CONCLUSIONS: The TAI is a reliable outcome measure for assessing transfer technique remotely.

RESUMEN

PURPOSE: To test the hypothesis that remote learning to teach clinicians manual wheelchair skills is efficacious. MATERIALS AND METHODS: A convenience sample of therapists (physical and occupational) and students were enrolled in pairs in a cohort study with pre- versus post-training comparisons. The intervention was a hybrid of self-study and hands-on practice paired with remote feedback for ten intermediate and advanced manual wheelchair skills. Participants practiced with self-selected frequency and duration, uploading a session log and video(s) to an online platform. A remote trainer provided asynchronous feedback prior to the next practice session. Capacity and confidence in completing the ten skills were evaluated using the Wheelchair Skills Test Questionnaire (WST-Q). Knowledge of wheelchair skills training and motor learning was assessed using a 62-item Knowledge Test. Secondary outcome measures included skill achievement, as confirmed by submitted video recordings, and participant feedback about the training. RESULTS: Across 41participants, scores were higher at follow-up compared to baseline for WST-Q capacity (73.9 ± 19.1 vs 16.8 ± 15.6, p < 0.001), WST-Q confidence (80.1 ± 12.2 vs 47.6 ± 18.2, p = 0.003) and knowledge (70.8 ± 7.5 vs 67.0 ± 5.4, p = 0.004). CONCLUSIONS: Remote learning can increase wheelchair skills capacity and confidence as well as knowledge about such training and assessment. This model should be further investigated as a delivery method for training rehabilitation professionals. CLINICAL TRIAL REGISTRATION NUMBER: NCT01807728.Implications for rehabilitationWheelchair skills training is one of the 8 steps of wheelchair provision as outlined by the World Health Organization.Wheelchair skills are not a core part of most clinical curriculums and many clinicians cite a lack of resources and uncertainty on how to implement wheelchair skills training into practice as major barriers to providing such training.Remote learning offers the benefits of structured wheelchair skills training with expert feedback on an individual's own schedule that is not afforded by one-day "bootcamp"-type courses or on-the-job training, which are how many clinicians currently learn wheelchair skills.In a sample of physical and occupational therapists and students, remote learning was effective at increasing capacity and confidence to perform manual wheelchair skills as well as knowledge of wheelchair training.

RESUMEN

OBJECTIVE: To determine if functional measures of ambulation can be accurately classified using clinical measures; demographics; personal, psychosocial, and environmental factors; and limb accelerations (LAs) obtained during sleep among individuals with chronic, motor incomplete spinal cord injury (SCI) in an effort to guide future, longitudinal predictions models. DESIGN: Cross-sectional, 1-5 days of data collection. SETTING: Community-based data collection. PARTICIPANTS: Adults with chronic (>1 year), motor incomplete SCI (N=27). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Ambulatory ability based on the 10-m walk test (10MWT) or 6-minute walk test (6MWT) categorized as nonambulatory, household ambulator (0.01-0.44 m/s, 1-204 m), or community ambulator (>0.44 m/s, >204 m). A random forest model classified ambulatory ability using input features including clinical measures of strength, sensation, and spasticity; demographics; personal, psychosocial, and environmental factors including pain, environmental factors, health, social support, self-efficacy, resilience, and sleep quality; and LAs measured during sleep. Machine learning methods were used explicitly to avoid overfitting and minimize the possibility of biased results. RESULTS: The combination of LA, clinical, and demographic features resulted in the highest classification accuracies for both functional ambulation outcomes (10MWT=70.4%, 6MWT=81.5%). Adding LAs, personal, psychosocial, and environmental factors, or both increased the accuracy of classification compared with the clinical/demographic features alone. Clinical measures of strength and sensation (especially knee flexion strength), LA measures of movement smoothness, and presence of pain and comorbidities were among the most important features selected for the models. CONCLUSIONS: The addition of LA and personal, psychosocial, and environmental features increased functional ambulation classification accuracy in a population with incomplete SCI for whom improved prognosis for mobility outcomes is needed. These findings provide support for future longitudinal studies that use LA; personal, psychosocial, and environmental factors; and advanced analyses to improve clinical prediction rules for functional mobility outcomes.

RESUMEN

OBJECTIVE: To determine the effectiveness of a web-based, direct-to-user transfer training program in improving transfer quality and maintaining improvements for up to 1 month after training as compared with a control group. DESIGN: Randomized controlled trial with participants randomized to an immediate intervention group (IIG) or waitlist control group (WLCG) that received the training after a 6-month delay. SETTING: Wherever the participants accessed the web-based training, likely the home environment. PARTICIPANTS: Convenience sample of full-time wheelchair users (N=72; IIG, n=34; WLCG, n=38 for between-group analysis, n=48 for combined within-group analysis) with spinal cord injury or disorder who were able to independently perform a lateral scoot transfer. INTERVENTIONS: Self-paced, web-based transfer training module. MAIN OUTCOME MEASURES: Transfer Assessment Instrument Questionnaire (TAI-Q) score at baseline, 1 month, and 6 months postbaseline (WLCG only), immediately posttraining, and 1 month posttraining. The TAI-Q is an 18-item self-assessment that covers several aspects of a quality transfer. RESULTS: The IIG significantly increased particpants' baseline TAI-Q score from 6.91±0.98 to 7.79±1.12 (P<.001) by 1 month posttraining. The WLCG also increased from baseline to the 1-month postbaseline assessment (from 6.52±1.13 to 7.00±1.09; P=.014), potentially from learning effects secondary to self-assessment with the TAI-Q. The extent of change over time did not differ significantly between the IIG and WLCG from baseline to 1 month (P=.169). However, significant improvements in TAI-Q scores were still evident after the training for the WLCG (P<.001). Those with a lower pretraining TAI-Q score and more shoulder pain were most likely to benefit from the training. CONCLUSIONS: Repeated TAI-Q self-assessments likely contributed to improved transfer quality, with web-based training having an additive effect. Wheelchair users are likely to benefit from transfer training and self-assessment of transfer quality in their home environments. This has the potential to decrease injury risk while avoiding barriers to in-person training.

RESUMEN

A problem in the Complex Rehabilitation Technology industry is the lack of standardization in the assessment for wheeled mobility and seating (WMS). The aim of this paper was to identify assessment tools commonly used by clinicians during WMS evaluations. After the tools were identified by a panel of 12 subject matter experts, a presentation at the 2018 International Seating Symposium in Vancouver, Canada and the 2018 European Seating Symposium in Dublin, Ireland polled attendees via the Sli.do polling application to determine professional opinions of each tool, resulting in face validity for use in wheelchair evaluations. The Lawshe Content Validity Ratio was used to convert this anecdotal data into numerical data, indicating which tools were most and least used by attendees. Finally, a literature search was conducted to determine the reliability, validity, and International Classification of Functioning, Disability, & Health domain for each measure. The findings indicate that while there are many standardized and reliable assessment tools available for wheeled mobility and seating evaluations, most clinicians use only a few standardized assessment tools during WMS evaluations.
